Abstract

Background/Aim. Intrathecal anaesthesia has been shown to increase sedation level. This study aimed to evaluate the effects of intrathecal applied fentanyl with levobupivacaine on intraoperative sedation and recovery room delirium. Materials and Methods. The study included 68 patients, ASA I–III, 55–85 years. One day preoperatively, the Confusion Assessment Method (CAM) and the Mini Mental Status Test (MMST) were applied and patients were separated into two groups. In Group L 2.5 mL levobupivacaine and in Group LF 2 mL levobupivacaine and 0.5 mL fentanyl were applied intrathecally. In a supine position, following a propofol IV 1 mg kg−1 bolus to obtain Bispectral Index (BIS) of 70–85, propofol infusion was started (1 mg kg−1 st−1). With observation of SpO2, BIS, and the Observer Assessment and Alertness/Sedation Scale (OAA/SS) with the haemodynamic values, the total propofol amount was calculated. Evaluations were made of pain severity (VAS), analgesic use, transfusion requirement, and recovery room delirium. Results. In the comparison within the groups, a significant decrease was determined in HR and MAP compared to the initial values (). A positive correlation was found between the BIS and OAA/SS values. The amounts of propofol used were similar between the groups. Conclusions. Intrathecal fentanyl and levobupivacaine had the same effect on sedation or BIS and fentanyl did not cause delirium.
